Only 1.5bn of the estimated 6bn land parcels worldwide have land rights formally registered in land administration systems. Many of the 1.1bn slum dwellers and further billions living under social tenure systems wake up every morning to the threat of eviction.

Roads are improved and maintained depending on its roles such as transport routes, minelayers of lifelines, refugee roads at disaster and also needs of users. To improve the roads safety and convenience, road authorities need the data to be used to comprehend 3D shape of the road space and its deformation quickly and accurately.

WAAS provides very precise navigation service, with both horizontal and vertical guidance over the Continental United States (CONUS) and a large portion of Alaska, Canada, and Mexico. Other countries and regions of the world also have fielded or are fielding similar systems. WAAS and each of these other systems are known as a Satellite Based Augmentation System, or SBAS.

Crustal movement before and after the Great East Japan Earthquake: Dr Shunji Murai, Dr Harumi Araki;
The importance of mitigation of GNSS vulnerabilities and risks: Renato Filjar, Darko Huljeni;
Assisting visually impaired using smart-phone sensors: Oluropo Ogundipe;

For the blind and partially sighted the visual cues which are a significant part of monitoring the environmental flow are either severely limited or non-existent. Thus the challenge is to be able to use man-made sensors and technology such as the smart phone based sensors to assist such individuals in monitoring the environment and collecting cues/ data about the environmental flow.
